Network requirements for VM migration

Latest response

I am trying to setup a RHEV3 system with 4 HP DL380 G7 servers ( 2 for manager and 2 for hypervisor ) connected to a iscsi  RAID.  Each RHEV-H server comes with four 1g nics.  I plan to use 2 bonded ( active/standby ) networks,  one for iscsi-storage and another for data traffic.  On the traffic bond network, I also plan to have dedicated VLANs for  management and  traffic. One thing i didn't find more detail is how VM migration is handled.  

Is there any pointers on how much bandwidth is needed for VM migration?   Also when a VM is migrated what is the role of the RHEV-M in the migration. Does the migration traffic go peer to peer or gets proxied via RHEV-M?
 
thanks
